Cooking Directions

Step 1

Position racks in lower third and middle of oven; preheat to 450°F.

Step 2

Break linguine into pieces about 3 inches long. Cook the broken linguine in a large pot of boiling salted water until al dente, 6 to 8 minutes. Drain in a colander and rinse under cold water until cool. Press to remove excess water. Transfer to a large bowl, toss with 1 teaspoon oil and set aside.

Step 3

Toss asparagus, scallions and bell peppers in a large bowl with the remaining 2 tablespoons oil, salt and pepper. Divide the vegetables between 2 large baking sheets, spreading them in an even layer.

Step 4

Roast for about 10 minutes, stir the vegetables and switch the positions of the baking sheets. Continue roasting, stirring occasionally, until the vegetables are tender and well-browned, 10 to 15 minutes more.

Step 5

Add the vegetables to the linguine and toss to combine. Add Parmesan and vinegar and toss again.
